Hi there, I am wondering if killing apps that I don't use will increase battery life or just freeing up some RAM?
If it does increase battery life, any app recommendation? I don't need it to auto kill, I can press it each time the phone boot. I tried some already actually, like Advance Task Killer but some apps labelled green can't be killed? I am not sure, I am new to this.
Thanks
You don't need a task killer at all, in fact it's better NOT to use one.
Also have a look at this post where I wrote a little about this.
Android is designed to kill apps on its own whenever it feels that your RAM is getting full. I used Killer apps and it only made my phone worse!
So its better not to use one

There are always a lot of running apps which waste a lot of ram and power..
This is significantly reducing battery life and overall performance..
Using task killer has no effect as those apps automaticaly start running again
Please suggest a remedie
Sorry to tell you, but you have to inform yourself about how Android OS works.
1. You don't need task killers - they are useless !
2. Apps are stored in RAM so that they can be relaunched faster.
3. Apps stored in RAM do not drain battery. Only active apps drain battery.
4. Check wikipedia for further info.
Thanx for dispeling my myth..
Can u also give me some suggestions 4 increasing battery life..
And also can u tell me an app that will tell me hw much battery is being consumed by each app or process on my phone?
For battery increasing try disabling 3G/Wi-fi/Bluetooth/GPS when not used. Put screen brightness at about 60%. I only do this and I always manage 2 days with moderate to intensive usage.
Download Spare Parts from Market. You can see there everything you want regarding to battery.
Task killers is there any advantage on using them ? Currently I am using one that kills as I lock my phone although in theory these apps are just booting back up in the background (services that is) isn't that hogging resources in its own right ?
So my question is do you use a task killer ?
Cheers
The consensus is that they're not useful. Use the back button to quit apps, and a battery monitor to monitor apps that abuse power.
If you see apps taking up RAM, that's a good thing - RAM is supposed to be utilized so that the phone can launch apps faster.
Do not use task killers!
Our beloved gs2 has lotsa memory and android's memory management is very powerful. So don't worry about ram usage. When the device runs out of ram/after an app is no longer required to be kept in memory, inactive and finished apps are removed from memory automatically.
Most of the apps, after exit are kept in memory for a faster launch next time. Idle apps doesn't consume any cpu or battery.
If you're worried about your cpu usage and battery drain, use watchdog from market to monitor misbehaving apps.
Use betterbatterystats to monitor what apps/services are causing wakelocks.

Then you can adjust the settings/uninstall apps that's causing battery drain.
Hi, I own a Xperia mini pro. My first android phone .I have rooted my phone. The phone's ROM hasn't been changed. I'm using root apps like CPU Master, Auto Manager Memory, SD card speed increase etc. Default launcher is GO launcher.
I had read in many forums that rooting a phone and using softwares like CPU Master may increase the battery life. Currently my average battery life is around 12-14 hours. It was the same when I hadn't rooted my phone. I leave HSDPA data transfer always on. That might be one of the contributors in draining the battery faster. I used to use Juice defender earlier. Though it seemed to increase my phone's battery life (mainly because of my setting to switch data transfer off when screen is off 'but' allow data transfer for only some selected apps even when screen is off), it used to make my phone laggy. I've used other apps like green power, tasker and others.. While they switch off data when screen is off, none of them have option to enable data for selected apps even when screen is off(which i need because most of my friends use apps like whatsapp, facebook messenger or gtalk to message me). I've also removed some system apps, like fun and downloads, popcap etc. Could I use any alternatives for the apps mentioned above which consume lesser battery? Or is improving battery life on rooting only possible when ROM and kernels are changed
Plz suggest an alternative to juicedefender that allows me to do what i want. And it'l be really helpfull if someone who has achieved prolonging his/her mini pro's battery life gives me some tips on the same.
33 1/2 hours since I posted this question. And still no reply.. I'm disappointed
Hope this helps.
Hi,
Bro u have a rooted phone , but you don't have a custom ROM that means that you can not overclock or under clock your mobile, so using cup master or set cpu will not help you.
Solution can be u an flash a new ROM having an overclocked kernel or you can flash a overclocked kernel to your current stock ROM or if you don't want to do any of this simply uninstall cpu manager as it will be eating unnecessary juice from your battery and not helping in any way.
Auto memory manager does improves battery life but only a bit, it basically controls the apps killing rate i.e. it manages how much RAM should remain free at all times helps improves performance of you phone, so don't use an aggressive profile because it will kill apps (background or paused or closed) very frequently which in turn will lead to use of your battery, instead use a mild or less aggressive or default settings this will improve both performance of your phone and use lesser juice as compared to a aggressive setting.
Also keep in mind since u r using Gingerbread so killing apps using task killers after every few minutes will not help , so u can uninstall task killers, also if u need a task killer it is already present in go launcher u can use that.
Juice defender is ultimate app which helps improves battery a lot, but u need to have optimized settings according to your needs.
My advice is use smart profiles by Antutu to create profiles for different timings i.e when you need 3g or wirelss or not as when your are sleeping you don't need wifi or 3g on.
Also best option of saving battery is reducing screen brightness.
You can reduce brightness to 20 % which you are inside the building or working under lights as the screen is properly visible.
And outside in bright sun you can use 35-50% brightness.
Keeping phone at 100% brightness will screw the battery life.
You can use LUX or ambident light senor for automatic brightness setting according to the day light or unnatural light or dark.
hope this helps you.

I forgot to mention point about serious battery saving settings.
1) Use lesser widgets only widgets you really need, as they are battery hogger.
2) Try to reduce push interval for email notification, facebook, twitter, weather widget because using 1-5 min push interval will use a lot of juice, try increasing interval to 30 minutes or more or use manual push if you don't need the notification updates every single minute pooping in. This part eats most amount of battery so if u can change the settings this will improve you battery life a lot.
3) Also watch if any unnecessary services are not running in background, because a lot of apps uses services which eats significant battery , so if there is a application which is not needed at all but is running unnecessary service u can uninstall it if you want, but this is not mandatory.
4) Lastly you can use watchdog app , it log the cpu usage by apps and will let you know which app is eating up a lot of juice. So u can find the culprit and find alternative app for that.

Do you guys use task manager? Why or why not?
Sometimes yes...not sure if you really need to with this phone. Just a little OCD on my end
Only when some app is making problems, otherwise no
I often run a kill once at bootup, and then after that only if an app seems to be holding wakelocks or eating excessive CPU.
There is no longer any valid reason for using a task manager for memory management purposes, only for killing wakelock/CPU hogs.
I use Autostart to kill a few things that like to start up on boot, then ATK just for killing wakelock/cpu apps as well.
Mainly FB/Engadget like to stay running when I exit them and cause my battery to get eaten away.
I usually push the "clear memory" button.
I do along with Advanced Task Killer. It kind of nice to know less things is running in the background eatting battery...
ahh, thanks for the reply. cause i was wondering if i should have it as a widget (to clear memory faster) or not (save battery).
I use it when apps are misbehaving or my phone is warm. Mostly its the engadget app.. It runs cpu at like 70% when in background for some stupid reason.

It's up to you if you want to put it as a wigget for easy access. I myself don't, because I hate clutter screen. It only take me 5 seconds to navigate to it.
All the time. just to make sure nothing drains my battery and nothing (especially Browser) is not continuously access internet when I outside WiFi.
Rarely. like others I use one to check and kill misbehaving apps.
I freeze or uninstall most unused apps and disable startup on some.

Not really. I use watchdog task manager to keep an eye on things (with a fairly low threshold - 30%), and it does a really good job. I also use Autostarts to stop a few things from starting up at all.
The app Clean Master claims it can extend battery life and device performance by killing apps--even offering a button to kill all apps. I thought killing apps was unnecessary since Android does this automatically when RAM is full and that killing apps manually actually drains battery life. What's the deal? Is swiping an app away from the Recent Apps List the same as killing an app? I currently do this often because the list is usually packed.
Thanks.
Clean Master actually does increase performance of your device, especially and lower end ones that have 512mb of ram to work with. However, this also decreases battery life by very little. Android does kill task automatically however as you said it waits until the memory is full which leads to a lot of lag and sluggishness. Swiping an app from the recent apps I believe does kill it. Personally instead of swiping my ROM supports "hardware back to kill" in which I hold down my back button to kill the app. It seemed to do a much better job than swiping.

So Clean Master does "decrease battery life by very little" and the claim that it saves battery life through killing apps is incorrect? This is at the expense of increased performance only if RAM is full, too. It seems that the term "killing apps" is very misleading even for Android users as it actually uses more battery life to kill the apps rather than leave them alone (because they use little to no resources in the background). If this is truly the case, then I guess I shouldn't worry too much about killing apps until my RAM is full and I experience lag. Still, I find it kind of surprising that such a highly rated and popular app claims one thing and does the other.
On a semi-unrelated note, is there some mod I can install on top of a ROM I'm using that lets me kill an app or display the Recent Apps List by long-pressing menu/back button? Or must I install a ROM that has this built-in feature?
Thanks.

Any task killing app such as auto memory manager, clean master, and so on decreases battery life, because it always using background resources. However, you most likely will never notice the difference in battery life lost since it is so negligible. I'm honestly not sure. I did a little bit of research and it usually pointed to that this function had to be in the framrwork of the rom. So my guess is you'd either have to modify the existing framework of a stock rom or just download a rom like Cyangonmod.
